The answer is vitamin D. This is actually a group of vitamins of similar molecular structure responsible for facilitating increased absorption of calcium, magnesium and phosphate from the gut. The most important of the vitamin D compounds are vitamin D3 and D2. While vitamin D can be obtained from your diet and supplements, the major source of vitamin D is from a chemical reaction dependent on skin exposure to the sun.

Answer:
1) The muscles need more energy as the breathing rate and heart rate increase to bring more oxygen into the body and remove carbon dioxide. More energy is needed to supply muscles with extra oxygen and remove carbon dioxide.
2) Glycogen in the muscles.
3) Rate and volume of breathing increases,
Cardiac output is increased,
Blood flow from nonessential organs is provided to the working muscle.
4) Muscle cells respire anaerobically when there is a temporary deficiency of oxygen during high intensity exercises.
5) Lactic acid.
6) Muscle fatigue is when the muscle cannot perform as normal (decline of ability) due to a result of vigorous exercise.
7) A temporary oxygen shortage in the body tissues due to exercise.
8) Oxygen+ Lactic acid goes to Carbon dioxide + water.
9) The body continues to respire in order to get more oxygen and remove carbon dioxide.
10) The heart rate and breathing rate stay high after exercise in order to repay the oxygen debt and remove carbon dioxide. They also have to reduce the acid based balance in the muscles to neutral.
11) Lactic acid can also removed by being converted into Glycogen. This involves the muscles as glycogen is a product of the muscles

There are several ways by which a skeletal system <span>help aid the body when its sick. Firstly, it helps in producing red blood cells in the body. It also helps in maintaining the level of calcium in the body. It also produces the stem cells that increases the immunity of the body. I hope that the answer has come to your help.</span>
